So you round to the second decimal place, giving you 43.59
A = oz of the solution A
b = oz of the solution B
The scientist knows that solution A is 45% salt and solution B is 95% salt. She wants to obtain 80 ounces of a mixture that is 65% salt.
a + b = 80
0.45a + 0.95b = 0.65*80
by solving the above system of equations you'll find····
a = 48 oz
b = 32 oz
~I hope this helped~
If it doesn't make since, I can try to switch up the wording ^^
Answer:
m<7 = 61
Step-by-step explanation:
These angles (<7, and <8) are adjacent to each other (they are next to each other), therefore they are supplementary (add up to 180).
180 - 119 = m<7
Answer:
70%
Step-by-step explanation:
Two Steps to Convert a Fraction to a Percent
Use division to convert the fraction to a decimal:
7/10 = 7 ÷ 10 = 0.7
Multiply by 100 to get the percent value:
0.7 × 100 = 70%
Therefore the answer is 70%.
Answer:
p = 40
Step-by-step explanation:
20/6 = p/12
20 × 12 = 6 × p
240 = 6p
p = 240/6
p = 40
